Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical committees. Each member body interested in a subject for which a
technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in
the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,
Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 18629-1 was prepared by ISO/TC 184, Industrial automation systems and integration,
Subcommittee SC 4, Industrial data.
A complete list of parts of ISO 18629 is available from the Internet.

ISO 18629-1 : 2004 (E)
Introduction
As the use of information technology in manufacturing has matured, the necessity for software
applications to inter-operate has become crucial to the conduct of business and operations in
organisations. To be competitive and maintain good economic performance, manufacturing
organisations need to employ increasingly effective and efficient systems. Such systems should result
in the seamless integration of manufacturing applications and exchange of manufacturing processes
between applications. Organisations should also be able to preserve and retrieve on demand the
knowledge contained in their business and operational processes, regardless of the applications used to
produce and handle these processes.

Many manufacturing engineering and business software applications use process information,
including manufacturing simulation, production scheduling, manufacturing process planning,
workflow, business process reengineering, product realisation process modelling, and project
management. However, each of these applications utilises process information in a different way, and
each representation of process information inherent to these applications is also different. Thus
interoperability is difficult to achieve. Consequently, these concerns have led to the development of a
process specification language (PSL) that complements the process representations utilised in
manufacturing engineering and business software applications. ISO 18629 provides a generic language
for process specifications applicable to a broad range of specific process representations in
manufacturing applications.
ISO 18629 provides semantics to the computer-interpretable exchange of information related to
manufacturing processes. Taken together, all the parts contained in ISO 18629 a language for
describing a manufacturing process throughout the entire production process within the same
industrial company or across several industrial sectors or companies, independently from any
particular representation model. The nature of this language makes it suitable for sharing process
information related to manufacturing during all the stages of a production process.

The process representations used by engineering and business software applications are influenced by
the specific needs and objectives of the applications. Therefore, the use of the process specification
language also varies from one application to another. A major purpose of the Process Specification
Language is to enable the interoperability of manufacturing processes between software applications
that utilise different process models and process representations. As a result of implementing process
interoperability, economies of scale are made in the integration of manufacturing applications.

This part and all other parts of ISO 18629 are independent of any specific process representation or
model used in a given application. Collectively, they provide a structural framework for
interoperability.
ISO 18629 describes what elements inter-operable systems should encompass, but not how a specific
application implements these elements. It is not the purpose of ISO 18629 to enforce uniformity in
manufacturing process representations. Objectives and design of software applications vary. Therefore
the implementation of an interoperable application must necessarily be influenced by the particular
objectives and processes of each specific application. This part of ISO 18629 provides an overview of
the principal concepts contained in ISO 18629, and guidance on selection and use of its parts.
